Heated ventilated seats?
I don't get it? My seats are putting out Hot air on my back when I turn on the vented seats function. I can feel the hot air from the passenger seats with my hands. And I made sure I pressed the button with the fan symbol (not the the one with the radiating seat bottom). My AUTO A/C is set around 75 degrees. It's really hot in Houston! Any suggestions?

Its because they're ventilated seats, not cooled seats. There is not a dedicated flow of cooled air that powers the seats but just a fan that circulated ambient air through it. It'll only blow as cool as the air under the seat.

I guess Texas heat was not considered in this design.

I see what you mean but no car I've had ever sent any air to the footwells while on auto in hotter temperatures.

That is the right name for our ventilated seats. I gave up this feature. When it's hot, it took forever for the fan to ventilate the heat under the seat. It takes me 20-30 mins to get home and my back never got better (I felt as if it was even hotter when the fan was on). I decided not to turn it on and learned that the seats cool down faster. It's a nice feature when not too hot but useless when it is hot. I got a nice front sun shade that covers pretty much all the windshield and always have the rear and side shades on. That seems to help.

Yes, I've decided the feature is pretty useless for me. For most drives, it's just going to blow the most undesirable air.

I've heard of RX owners taking a piece of carpet (you could use anything really) and using it to redirect the air from the vents under the seats (that normally cools the rear passengers) so that it stays mostly under the seats. And therefor cooler air for the ventilated seats.

I need to double check, but I thought the ventilation option pulled air through the seat, not push. The reason I say that is when I turn mine on, and lean forward, I can hear air noise similar to a vacuum sound. I'll check the owners book.
